It would be nice to be able to rearrange the order of Materials/Subproducts on a Products page. This would help for organizing if new materials were added and assigned a specific operation. Then visually you could rearrange them so that all of the materials assigned to that one operation were together. Currently it is set by the order you input the Materials/Subproducts and if you want a new material to move up on the list, you have to delete from the bottom up.
